Did you know that there are 29 species of woodlice (I didn’t)? And quite a lot of them are really hard to specify, because, and this is the really cool part, it is the male one would use to determine what kind of woodlice one got hold of. And in some species of woodlice the males are really rare.
In other species, there are no males at all!

The name in the headline is the latin name for the seawoodlice.

Cool right 😉
You might be wondering where I’m going with all this, and you should.
